  • Method of determining the state of charge of a battery of an electronic appliance
    Patent number: 10073144
    Abstract: A state of charge of a battery is estimated in several iterations, each iteration including: acquiring a measurement of intensity of current supplied by the battery, acquiring a measurement of voltage supplied by the battery, estimating a first state of charge of the battery based on a first estimated state of charge obtained upon a previous iteration and on the current intensity measurement, estimating a value of intensity of current supplied by the battery based on the voltage measurement and on a state of charge of the battery obtained upon the previous iteration, and calculating a corrected state of charge by adding to the first estimated state of charge a corrective term obtained by the product of a first correction gain multiplied by a factor representative of a difference between the estimated and measured current intensities.
